<h2><b>set xlab</b></h2>

<p>
<code>set xlab <i>option</i></code>

<p>
Controls the format of X-axis tick mark labels. The <code><i>option</i></code>
argument may be one of the following:

<ul>
<code>on&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code>
labeled tick marks are drawn with the default characteristics<br>
<code>off&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code>
labeled tick marks are not drawn<br>
<code><i>format</i>&nbsp;&nbsp;&nbsp;</code>
gives a C-language template for conversion of the label value to a string <br>
</ul>

<p>
<h3>Usage Notes</h3>
<ol>
<li>If the X axis represents longitude, then the default behavior is to append an 
"E" or "W" to all tick mark labels depending on the hemisphere. 
<p>
<li>Changes to the X-axis tick mark labels are reset by <a
href="gradcomdclear.html">clear</a>, but not <a
href="gradcomddisplay.html">display</a>.
</ol>

<p>
<h3>Examples </h3>
<ol>
<li>This command would cause all X-axis labels to have 2 digits after the decimal point:
<ul><code>set xlab %.2f </code></ul>
</ul>
